Romney said the plan introduced by House Budget Committee chairman Ryan (R-Janesville) “does not balance the budget on the backs of the poor and the elderly … It instead preserves Medicare and preserves Social Security.”

Look, this really isn’t complicated. Paul Ryan’s budget plan is simply brutal towards the poor and working families. Romney doesn’t have to like it, but he really shouldn’t lie about it.

House Budget Committee Chairman Paul Ryan’s budget plan would get at least 62 percent of its $5.3 trillion in nondefense budget cuts over ten years (relative to a continuation of current policies) from programs that serve people of limited means. This stands a core principle of President Obama’s fiscal commission on its head and violates basic principles of fairness.

While giving a massive tax break to the wealthy, the Ryan budget plan Romney is so fond of slashes funding for Medicaid, food stamps, and other for low-income programs, nearly all of which Ryan’s plan would eliminate over the next couple of decades.

As the CBPP’s Robert Greenstein put it, “[T]he Ryan budget would impose extraordinary cuts in programs that serve as a lifeline for our nation’s poorest and most vulnerable citizens, and over time would cause tens of millions of Americans to lose their health insurance or become underinsured.” He added that Ryan’s plan “would cast tens of millions of less fortunate Americans into the ranks of the uninsured, take food from poor children, make it harder for low-income students to get a college degree, and squeeze funding for research, education, and infrastructure.”

If this doesn’t “balance the budget on the backs of the poor,” for crying out loud, what exactly would such a budget plan look like?

As for “preserving” Medicare, the Ryan plan that Romney supports would turn Medicare into a voucher program, scrapping the guaranteed benefit altogether; weaken Medicare solvency; and bring back the Medicare Part D prescription drug “donut-hole.”

So, what are we to make of Romney’s comments this morning? He’s either lying or he hasn’t read the budget plan he’s endorsed. It’s one or the other.
